OBSERVATION-WINDOW.

Specification of Letters Patent.

Patented Oct. 14, 1919.

Application filed November 9, 1917. Serial No, 201,070.

To all whom it may Concern.'

Be it known that I, ROBERT I. BREESE, a citizen of the United States, residing at New York city, N. Y., have invented certain new and useful Improvements in Observation- Vindows, of which the following is a clear, full, and exact description.

This invention relates to means for providing clear vision under all conditions particularly in stormy and wet weather, and may be advantageously employed in the observation windows of pilot house cabins, engineers cabs, motor-men platforms of street cars, periscopes for submarines, the windshields of automobiles, and for other a'nalogous uses.

It is a matter of common knowledge and experience that the ordinary window in the above mentioned fields of service is of little or 'no use for'observation purposes in rainy `and snowy weather, since the rain, sleet or snow accumulating on the glass 'soon obstructs the view.

Hand operated cleaning devices of various kinds have been employed to improve the vision under such circumstances, but none, so far as I am aware, hasv accomplished the purpose of the present invention, namely, to automatically provide a clear view at all times and under all conditions.

In the drawings which show the preferred embodiment of my invention,

Figure 1 is a front elevation of the device shown as applied to an ordinary window pane;

Fig.. 2 is a, side elevation of the device, with the upper part thereof 'insection;,-

Fig. 3 is a detail section of the fastening means betweentherotating shaft and disk;

Fig. 4 is a front elevation of a modified form of the device;

Fig.` 5 is a section taken along line 5 5 of Fig. 4 of said modification;

Fig. 6 is a front elevation of still another modification; and

Fig. 7 is a side elevation of said modification shown in Fig. 6.

Referring more particularly to the drawings, 1 indicates a rotating member for permitting vision therethrough, which may be in the form of a transparent disk such as of glass, celluloid and the like. In some cases a rotating wiping arm acting upon a stationary pane of glass may be employed Y as shown at 1 in Figs. 6 and 7, it being understood that the Speed of rotation of said arm 1 is sufficient not to obscure the vision therethrough. Preferably, however, I employ a transparent glass disk for the member 1. As shown, disk`1 is securely fastened at its center upon the outer end of a rotating shaft 2, which in turn is carried in a suitable bearing 3. The inner end of said sha'ft 2 has fixed thereto a driving pulley 4 operated from any suitable source of power, not shown, by a belt 5.

The shaft 2 is carried through its bearing 3 upon a .universally adjustable support comprising a standard or bracket 6 and a cylindrical post 7 The post 7 is pinned at its upper end to the 'bearing 3 at 8, and is slidably and rotatably received within a.

clamping collar'9 so that said-post 7 ma)r 'beboth adjusted vertically and to different swinging positions within said sleeve. -The clamping sleeve 9 is of the ordinary split collar construction, arranged to be held together by bolt and nut 10, extending hori- 'zontally fromA the upper end of standard 6.` The sleeve 9 is adjustable around the horizontal axis ofthe bolt'10, and is maintained in its various adjustments by the coacting toothed-clutch portions 11 and 12,

one of which is integral with the stand-ard 6 and the other with the sleeve 9.

In adapting this observation device to an ordinary window pane, such as 18, I preferably provide weather-proof packing means between the stationary borderof thepane and the periphery of the rotating disk. This packing means may be suitably formed by opposed ring clamps 13 and 14, one on each side of the pane 18 and disk, and held together lby a series of bolts 15. The inner periphery of said clamps when held together provides a suitably shaped groove which maybe lined with soft felt, such as 16, for

Aresilient contact against the periphery of the disk 1, and the outer peripheryof said clamps 13 and 14 also forms a groove which may be lined with soft rubber 17 for firm bearing against the edges of the window pane 18. By meansof the adjustable support for the shaft 2 above referred to, the rotating disk 1 may be properly positioned with respect to the window pane 18 while the support itself may be attached to any suitable base adjacent said window.

Suitable means for firmly securing the disk 1 to the shaft 2, to be df'iven thereby, is shown in detail section, Fig. 3, and consists of a post 19 formed with a headed porsaid.

5. An observation Window, comprising a rotating transparent disk, said rotative Speed being sufficient to remove by centrifugal force such deposits on said member as A might tend to interfere with the vision therethrough, a stationary border portion surrounding the periphery of said disk and Weather-proof packing between said border portion and said disk, a rotating shaft for carrying said disk independently of support from said border portion, a support for said shaft capable of universal adjustment for alining said disk with said border portion comprising a post headed at one side of said disk and having a hollow shank extending therethrough to the other side of said disk, said shank 'being screw-threaded eXteriorly and interiorly for receiving a clamping nut for said disk upon its exterior and a threaded end of said shaft within its interior, and a lock nut for securing said shaft Within said post shank.
